I am developing a boot-loader on MC9S12XE family with Classic CodeWarrior, I want to add a descriptor for the application code, and it should contain an address which is application code '_EntryPoint' (i.e. the address store in application's reset vector), my problem is how to allocate the '_EntryPoint' banked address to a uint32_t integer?
It is an example of my problem, if I use the type 'tIsrFunc' to allocate '_EntryPoint' is OK but 16 bit value, e.g. 0x1234U.
If I cast '_EntryPoint' to a uint32_t, the value will be shift left four bits, e.g. 0x00123400UL.
How do I cast a backed function address to uint32_t without shifted left four bits?
typedef void (*near tIsrFunc)(void);
typedef struct APP_TRY_ADDR_S
const APP_TRY_ADDR_T m_TryAddr =
&_EntryPoint, /* it is OK, but 16 bit only */
(uint32_t)&_EntryPoint, /* it is wrong, the value shifted left four bits */
